IVORY BUTTON.

Specification of Letters Patent.

Application filed May 17, 1909.

Patented Aug. 23, 1910. Serial No. 496,551.

To all whom it may concern:

Be it known that I, WILLIAM GUSTAV SQHIMMEL, a subject of the Emperor of Germany, and resident of Schmfilln, in the Duchy of Saxe-Altenburg, Germany, have invented certain new and useful Improvements in Ivory Buttons, of which the fol lowing is a specification.

This invention relates to buttons and it has for its objects among others to provide a simple, cheap, yet strong and durable ivory button which shall be light and capable of manufacture without danger of splintering the ivory.

Other objects and advantages of the invention will hereinafter appear and the novel features thereof will be particularly pointed out in the a pended claim.

The invention is 0 early illustrated in the accompanying drawings, which, with the numerals of reference marked thereon, form a part of this specification, and in which Figure 1 is a substantially central section through the ivory body with the cap in elevation. Fig. 2 is a substantially central section through the completed button. Fig. 3 is a view taken at right angles to Fig. 2. Fig. 4: is a section on the line AB of Fig. 3.

Like letters of reference indicate like parts throughout the different views.

Referring to the drawings, a designates the body portion of the button of ivory or like material formed with a cavity 6 which is designed to receive the enlarged portion of the cap 0. The cap is normally of the form shown in Fig. 1. The body portion of the button is hollowed out and the cavity 6 is formed in the thickened portion thereof. This cavity is conically enlarged toward its inner end. The cap with its enlarged portion is introduced into the cavity and by suitable means, as the pressing stamp or die, this enlarged portion is forced into the cavity, as seen in Fig. 2, so as to firmly connect it with the body of the button.

The shank of the cap is formed with slits (Z of any suitable shape, preferably substantially such as shown, in order to permit of the sewing 0f the shank of the button to the material. The shank is of suflicient length to permit of the button being attached to the material by reason of the slits being brought a sufficient distance from the material, so that the button is firmly held in place and yet allows of it assuming the oblique position necessary for buttoning it without breaking off, as frequently happens with buttons of this class.

The compression of the cap into the concavity serves to firmly hold the cap in place and the formation of the cavity serves to decrease the weight of the button while the rounding off at the edge of the button body prevents splintering of the ivory usually experienced in this class of buttons:

What is claimed as new is As an improved article of manufacture, a button comprising a body portion of substantially hemi-spherical shape hollowed out and formed with a cavity communicating with the hollowed out portion, said cavity being conically enlarged toward its inner end, a cap of tubular form conically enlarged at its larger end with said enlarged end forced into said cavity and forming a dovetailed connection therewith, the outer end of the cap being closed and the shank portion thereof formed with longitudinal tapered slits, the outer end of the cap extending beyond the largest diameter of the body portion and the annular shoulder between the shank and the enlarged end being disposed outside said cavity and within the hollow of the body portion.

In testimony whereof I aiiix my signature.

WILLIAM GUSTAV SCHIMMEL.

In the presence of F. HnPHoRN, CHARLES NEUER.
